TransAlta Renewables Reports First Quarter 2018 Results

Adjusted funds from operations(1) increased $14 million over Q1 2017; and

Cash available for distribution(1) increased approximately 16% year-over-year.

TransAlta Renewables Inc. (“TransAlta Renewables” or the “Company”) (TSX: RNW) today reported its financial results for the three months ended March 31, 2018. Comparable EBITDA of $111 million was consistent with last year. Cash available for distribution for the first quarter was $96 million, an increase of $13 million compared to 2017.

Reported net earnings attributable to common shareholders increased $39 million primarily as a result of the Class B shares fair value loss of $44 million in the prior year, and higher finance income of $15 million this year, which was partially offset by a lower foreign exchange gain of $25 million.

“Results for the quarter were strong and highlighted the stability in the cash flows from our business,” said John Kousinioris, President. “We are now focused on the construction of our Kent Hill wind farm expansion and progressing our two new US Wind Projects.”

2018 Highlights and Subsequent Events

On February 20, 2018, we entered into an arrangement to acquire two construction-ready wind projects in the Northeast United States. The wind development projects consist of: (i) a 90 MW project located in Pennsylvania that has a 15-year power purchase agreement; and (ii) a 29 MW project located in New Hampshire with two 20-year power purchase agreements (collectively, the “US Wind Projects”). A subsidiary of TransAlta Corporation (“TransAlta”) acquired the 90 MW project on March 1, 2018, whereas the acquisition of the 29 MW project remains subject to certain closing conditions.

On April 20, 2018, we acquired an economic interest in the US Wind Projects from a subsidiary of TransAlta pursuant to the terms of the arrangement entered into on February 20, 2018. The remaining construction and acquisition costs of the US Wind Projects are to be funded by TransAlta Renewables and are estimated at US$240 million. We expect to fund these costs through existing liquidity and tax equity.

On May 1, 2018, we entered into a contract with a leading blockchain company to supply up to 35 MW of power and provide space at our Sarnia industrial park. The contract has a 5-year term with an extension option for up to an additional five years.

TransAlta Corporation hosted its Annual General Meeting on April 20, 2018, during which it was announced that Donald Tremblay, former Chief Financial Officer, had decided to leave TransAlta and the Company effective May 8, 2018, and has relocated to eastern Canada. The Company thanks Mr. Tremblay for his contributions and leadership over the past four years. Todd Stack, TransAlta's Managing Director and Corporate Controller, has been appointed as Chief Financial Officer of TransAlta Renewables.

2018 Outlook

TransAlta Renewables reaffirms its financial outlook for 2018 which was released on February 23, 2018 and is outlined in the table below.

The 2018 outlook includes expected revenues from long-term contracts and the sale of green attributes. We expect renewable energy production from our wind and hydro assets to be in the range of 3,400 to 3,800 GWh. Gas-fired generation primarily receives compensation for capacity, and accordingly, production is not a significant indicator of that business. TransAlta Renewables will continue to focus on growing cash available for distribution through the development and acquisition of highly diversified and contracted assets.

Notes

(1) Comparable EBITDA refers to earnings before interest, taxes, depreciation and amortization including finance lease income and adjusted for certain other items. Adjusted funds from operations includes the deduction of sustaining capital expenditures and distributions to non-controlling interests and excludes the effects of timing and working capital on distributions from subsidiaries of TransAlta in which the Company holds an economic interest. Cash available for distribution refers to adjusted funds from operations less principal repayments of amortizing debt. These items are not defined under International Financial Reporting Standards (“IFRS”). Presenting these items from period to period provides management and investors with the ability to evaluate earnings and cash flow trends more readily in comparison with prior periods' results. Refer to the Non-IFRS Measures section of the MD&A for further discussion of these items, including, where applicable, reconciliations to measures calculated in accordance with IFRS.

(2) Includes production from the Wyoming Wind Farm and excludes Canadian and Australian gas-fired generation. Production is not a key revenue driver for gas-fired facilities as most of their revenues are capacity based.
